INKSTAN D.

SPECIFICATION forming part of Letters Patent No. 418,988, dated January '7, 1890.

Application filed September 20, 1889. Serial No. 324,593. (No model.) Patented in Germany December 14, 1888, No. 17,828.

To aZZ whom it may concern- Be it known that I, MARTIN SCHREIBER, of Nuremberg, in the Kingdom of Bavaria and Empire of Germany, a subject of the Emperor of Germany, have invented certain new and useful Improvements in Inkstands, (for which I have obtained Letters Patent in Germany, No. 47,828, dated September 14, 1888, in the name of Johann Bammess,) of which invention the following is a specification.

The object of my invention is to provide an inkstand which is automatically closed by placing the pen-holder in a suitable receptacle provided for the same on the inkstand, and is automatically opened as soon as this pen-holder is removed from said receptacle.

The invention consists of the combination, with a casing, of levers pivoted in the same, a pen-holder-receiving socketsupported by said levers, a rock-shaft, atransverse lever mounted on said rock-shaft and serving to operate one of said socket-supporting levers, a vertical shaft,a sleeve surroundingit, both having arms, a pawl-arm on the rock-shaft adapted to act on the arms of the rod and sleeve, and laterally-swinging cover-sections connected with the shaft and its sleeve.

The invention consists, also, in the construction and combination of parts and details, as will be full; described and set forth hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view of my improved inkstand. Fig. 2 is a plan view of the operating mechanism, the ink-receptacle being removed.

Similar letters of reference indicate corresponding parts.

The mechanism is contained in a hollow metal casing or, provided in its top with a recess a for receiving a bottom plug a projecting downward from the ink-receptacle (4 which is shown in dotted lines. Two hemispherical cover-sections a, which can swing from and toward each other laterally, inclose the ink-receptacle, and said hemispherical cover-sections are secured to two arms a projecting, respectively, from a vertical shaft q and a sleeve p, surrounding said shaft. The shaft (1 is provided at its lower end with an arm 0, and the sleeve 19 is provided with an arm 0 at its upper end. On a standard cl on the upper surface of the bottom of the casing to the rock-shaft 7c is mounted, on which is fixed the rocking lever m, carrying at one end a weight n and at the opposite end a roller 7. A bent lever f has one end mounted to rock in a standard 0 on the upper surface of the bottom of the casing a. Part of said lever rests on the roller 0', and the free end of said lever passes through a transverse sleeve g in the lower end of a rod g, on the upper end of which the receptacle or socket h for receiving the pen-holder is secured. A brace i, secured to the rod g, is extended over to one side of the lever f to prevent lateral movement and to guide the same. An additional bent lever 6, also mounted to rock in the standard 0, has its free end passed through a transverse sleeve 9 also on the rod g, said two levers e and f serving for the purpose of giving the rod g and pen-holder socket h a vertical movement. A cam-arm m, secured 011 the rocking shaft 70, is provided at each end with a notch Z for receiving the bent ends of the arms 0 and 0 011 the shaft q and sleeve 19, respectively.

The operation is as follows: When the penholder is placed into the socket it, its weight presses down said socket and the rod g, whereby the rear ends of the levers c and f are pressed down, and as the lever f rests on the roller 7" that end of the rocking lever n carrying the roller '1' is pressed downward and the end carrying the weight n is raised. Thereby the rocking cam-arm m on the shaft 7.; is swung so as to turn the shaft (1 and sleeve 19 in such a manner that the cover-sections a swing toward each other and inclose the ink well or bottle a As soon as the pen-holder is removed the weight n swings downward, that end of the lever 01 on which it is secured causing the opposite end of said lever n to press upward the lever f, whereby the cam-arm m is swungin such a manner as to turn the arms 0 and 0 on the shaft q and sleeve 19 in the inverse direction, whereby the cover-sections a are swung from each other and the ink-well is exposed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a casing, of levers pivoted in the same, a pen-holder-receiving socket supported by said levers, a rock-shaft, a rocking lever fixed on said rock-shaft and serving to operate one of said socket-levers, a vertical shaft, a sleeve surrounding the shaft-arms on the shaft and sleeve, a cam-arm on the rock-shaft adapted to act on the arms of the rod and sleeve, and laterally-swingingcover-sections connected with the shaft and its sleeve, substantially as set forth.

2. The combination, with acasing, of swinging levers mounted in the same, a pen-holderreceiving socket supported by said levers, a rockyshaft in the casing, a rocking lever on said rock-shaft, .a Weight on one end of said rocking lever, an anti-friction roller on the opposite end on which anti-friction roller one of thepen holder-socket-supporting levers rests, a cam-arm on the rock-shaft, a vertical shaft, a sleeve surrounding it, arms on said shaft and sleeve, on which arms the opposite ends of the cam-arm can act, and laterally- 1 my invention I have signed my name in pres- 3 5 ence of two subscribing; Witnesses.
